Female beagle dogs (11-16 kg) were divided into 2 groups: 1. Normal Sodium and high Water Intake (NSWI): 2.5 mmol Na, 3.55 mmol K, 91 ml H2O, and 277 kJ per kg body mass and 24 h (31 24 h-balance studies with 11 dogs). 2. High Sodium and high Water Intake (HSWI): Same diet as NSWI but 14.5 mmol Na x kg body mass-1 x 24 h-1 (55 24 h-balance studies with 21 dogs). The 24 h-balance studies were performed after different periods of time after onset of the respective diet (dogs in metabolic cages). Plasma sodium concentration (PNa) on NSWI was 148.4 +/- 2.6 mmol x 1(-1), whereas it was lower on HSWI (145.9 +/- 2.4 mmol x 1(-1). The lower plasma aldosterone concentration (PAC) on HSWI (24 +/- 8 pg x ml-1) compared to NSWI (67 +/- 38 pg x ml-1) may account for the lower PNa on HSWI. 24 h-sodium excretion was 93.6 +/- 6.5% of intake (%i) on HSWI and 91.5 +/- 20.7% i on NSWI. 24 h-water excretion was not different between both groups (81 +/- 7% i).

The most prevalent infections in mouse stocks were caused by Mouse hepatitis virus (MHV), Minute virus of mice (MVM), Theiler's encephalomyelitis virus (TEMV), Reovirus type 3 (Reo3), Sendaivirus, and Pneumonia virus of mice (PVM). In mice no infections with Lymphocytic choriomeningitis virus (LCM), Polyomavirus, Mouse adenovirus, and K-virus were recorded. Only two colonies were infected by Ectromelia virus. The first six virus infections of mice were also found in rat colonies as well as the rat-specific Coronaviruses (Sialodacryoadenitisvirus--SDA, Rat corona virus--RCV) and Parvovirus (Kilham rat virus--KRV, Toolan H-1 virus) being endemic. Antibodies to Bacillus piliformis were detectable in about 50% of rat stocks screened. This is in contrast to the mouse, where only about 10% of the colonies were found to be positive. A similar picture was seen for M. pulmonis which is primarily an infection of the rat. In mice no case was detected during the last two years. The number of investigations performed from guineapig, hamster and rabbit colonies was relatively low. Nevertheless, antibodies against the following antigens were detectable: In guineapig stocks: Reo3, PVM, Sendai, Simian virus 5 (SV5) and B. piliformis; in rabbits: Reo3, Sendavirus, SV5, and B. piliformis; in hamsters: PVM, LCM and B. piliformis.

Lipid peroxidation is connected with the formation of reactive oxygen species and organic radicals characterized by the chemiluminescence with the amplifiers luminol and lucigenin.

As stress-inducing parameter crowding of the animals was used. 220 Syrian hamsters were kept individually (controls) or with 3, 5, 7 animals per cage. The crowded animals showed a significant decrease in mean survival time. This was linked to a histopathological examined significant increase in the extent and incidence of amyloidosis in several organs of both male and female hamsters. The kidneys and adrenals were most affected. Chronic inflammation as one probable amyloidosis-inducing factor, was not related to the observed morphological alterations. Furthermore the increase of amyloidosis was statistically not connected with an age-dependent development of amyloidosis.
